The Fisher FS20D ultrasonic cleaner has a sweep frequency feature that eliminates standing waves and creates consistent cavitation throughout tank. Controls are located above and behind cleaning tank and easily accessible. Additional features include ultrasonic power tracking to track operating frequency of cleaner; always delivering the same power, 40kHz rugged industrial transducers, a chemical-resistant body made of plastic, and tank drains with a valve incorporated. The Fisher Scientific FS20D ultrasonic Cleaner with timer is powerful enough to remove heavy oils, buffing compounds, proteins, consistent enough to manage difficult laboratory cleaning, and safe enough for delicate components or fine jewelry.

All of our equipment is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
